🚀 Automate Telegram Group Voice Note Sharing with PHP

Looking to deliver voice notes, audio recordings, or spoken messages to Telegram groups directly from your PHP applications? This comprehensive guide walks you through sending voice note files (OPUS format) to Telegram groups using PHP and the WhatsMate Telegram Gateway REST API. Perfect for PHP developers building web applications, content management systems, or automation tools that need reliable group voice messaging capabilities.

📋 Prerequisites

Before you begin, ensure you have:

  1. A WhatsMate Telegram Gateway account - Required for API access (sign up for a 2-week trial)
  2. Group registration - The Telegram group must be registered with the Gateway first
  3. PHP development environment - PHP installed and configured (version 7.0 or higher recommended)
  4. Basic PHP knowledge - Familiarity with PHP programming and web development concepts
  5. Web server access - Ability to run PHP scripts on a web server (Apache, Nginx, etc.)
  6. Voice note file ready - Have the OPUS file you want to send available on your server
  7. cURL extension enabled - Required for making HTTP requests to the API

⚠️ Important: Telegram groups must be registered with the WhatsMate Telegram Gateway before they can receive messages. Unregistered groups will not receive any messages from the Gateway. Registration instructions are available on the official WhatsMate site.

📝 Step-by-Step Implementation

Follow these steps to send your first voice note file to a Telegram group from a PHP application:

1. Copy the PHP Code Template

Start by copying the following source code into your PHP file:

2. Configure a few Parameters

Customize these key parameters in the PHP code:

  • Lines 2-4: Replace YOUR_INSTANCE_ID_HERE, YOUR_CLIENT_ID_HERE, and YOUR_CLIENT_SECRET_HERE with your Telegram gateway credentials
  • Line 6: Replace /tmp/martin-luther-king.opus with the path to your OPUS voice note file on your server
  • Line 9: Replace anyname.opus with the desired filename for the voice note
  • Line 10: Replace I have a dream with an optional caption for your voice note
  • Line 13: Replace Muscle Men Club with your target Telegram group name
  • Line 14: Replace 12025550108 with the phone number of the group admin (including country code)

3. Upload to Your Web Server

  1. Upload your PHP file to your web server (e.g., send-telegram-group-opus.php)
  2. Ensure your OPUS voice note file is accessible at the path specified in line 6
  3. Verify PHP has read permissions for both the script and voice note file
  4. Ensure the cURL extension is enabled in your PHP configuration

4. Send Your Voice Note

Execute the PHP script to deliver your voice note to the Telegram group:

Via web browser (for testing):

# Navigate to your script URL in a browser
https://yourdomain.com/path/to/send-telegram-group-opus.php

Via command line (for automation):

php send-telegram-group-opus.php

Via cron job (for scheduled sending):

# Add to crontab for daily execution at 9 AM
0 9 * * * /usr/bin/php /path/to/send-telegram-group-opus.php
